I am an Indian Passport Holder and have obtained E-visa for Turkey. Upon arrival in Turkey, will the Immigration authorities in Istanbul, stamp/ paste another Visa on Arrival on my Passport? If yes, then how many pages in Passport are required to be free?

I haven't been to turkey since the e-visa thing started, but before it started, the thing they pasted into your passport was about the size of a quarter page, if I recall correctly. With the stamps, it probably needs a half page. The stated requirement might well be one page, however, but I doubt that they would bee asking for more than that. Hopefully someone who's been there more recently than I will be able to shed some more light.
